Abstract: An apparatus and process or mixing granules and/or powders and/or liquids in rubber production plants, including: a mixer/extruder device for the production of a basic heterogeneous mixture; a plurality of distribution lines associated with said mixer/extruder device to supply the device itself with respective powdered and/or granulated and/or liquid products; the mixer/extruder device mixing the powdered and/or granulated and/or liquid products to obtain said heterogeneous mixture; at least one distribution line of a powdered product includes a pre-mixer arranged upstream of said mixer/extruder device to pre-mix said powdered product with at least one liquid product, preferably oil.

Abstract: A fluid control system in pneumatic conveying ducts of powdered or granular material, comprising: a supply source of a pressurized gas for transporting said powdered or granular material; an injection line of said gas to put said source in fluid communication with a conveying duct inside which the material is conveyed; a self-regulating pressure valve arranged on the injection line between the source and said duct; a control member of the self-regulating valve to provide a control signal to said valve representing a pressure value, said valve maintaining the gas flow supplied in said duct constant; and a flow and flow rate meter, arranged on the injection line upstream of the valve to transmit a flow and flow rate value to said control member.

Abstract: Apparatus and process for the conditioning of granules, powders and/or liquids, including: a hopper for containing the granules, powders and/or liquids equipped, on an external surface thereof, with at least one manifold defining a respective duct in fluid communication with the inside of said hopper; at least one blower member associated with said duct for delivering a flow of mixing gas or other gaseous mixing means of the granules, powders and/or liquids inside the hopper; and a first member for conditioning the flow of mixing gas arranged upstream of said blower member to adjust at least the pressure and/or humidity and/or temperature values and/or to supply the flow with an additive in a liquid or gaseous or vaporous form.
